Vent question

Hello:

I am by no means a plumber so am looking for some advice.

I've lived in my current home about 1.5 years, today I noticed a sewer gas smell in an upstairs bathroom. Upon further investigation it seemed to be coming from the bathroom exhaust fan. If I turned the fan on the smell went away, but came back as soon as the fan was off.

Ascending to the attic, it appears that the 2 bathroom fans upstairs share a common vent through the roof with the waste stack.

That seems like a problem to me but what do I know. Is that a problem? If so what't the easiest way to fix it? It probably involves a new stack through the roof for just the bathroom fans huh?

Thanks!

I wish you would post a picture of this; if I'm reading it correctly it's a very bizarre setup. If indeed the two bathroom fans are tied into a plumbing vent stack, it's a terrible job and should be fixed. I'm not sure if you can tie the fans together or not; a call to the fan mfg would answer that, but they should NOT be venting into the plumbing.
